Hainan Steel News: strength steel components Maintenance clothes

    Hainan has a high strength steel the characteristics of light weight, increased power and speed, has been widely used in the construction industry, and the steel structure outstanding ductility and shock resistance, short construction time, is increasingly used in high-rise construction.

    But Hainan steel resistant to high temperatures is not very good, in case of fire just a quarter of an hour of time, the temperature of steel will rise to over 540 degrees, the high temperature steel easily deformed, and then led to the accident, and therefore fireproof coatings produced.

    Slim or thin steel structure fire fire insulation fire retardant coating layer principle is expanded upon by the fire foam, foam constituting the foam layer not only cut off the oxygen, but also because its texture is loose and has excellent heat insulation performance, delay heat transfer to the substrate is maintained speed; the physical chemistry analysis, process foam layer coating expansion foam generated because the volume expansion of showing an endothermic reaction also consumes calories burned when conducive drop system temperature, the role of these areas, so that fire retardant paint fire insulation have a significant effect.

    Principle of fire insulation on the steel member coated thick steel structure fire retardant coating is the coating does not substantially affected by fire when fire retardant paint volume change, but the coating is very low thermal conductivity, heat transfer delay to the insured base speed, fireproof paint coating itself is non-combustible, steel members from the barrier and prevent heat radiation, avoiding the flames and high temperature direct attack on the steel members.
